I found the CGPA distribution for Foundation Level of IIT-M BS Degree in one of the groups. Total students considered: 27,449.

Based on the chart data:

CGPA distribution:

• 6-7 CGPA: 31.04% → ∼8,520 students
• 7-8 CGPA: 22.58% → ∼6,198 students
• 5-6 CGPA: 16.64% → ∼4,567 students
• No CGPA: 11.97% → ∼3,286 students
• 8-9 CGPA: 11.28% → ∼3,096 students
• 9-10 CGPA: 4.89% → ∼1,342 students
• 4-5 CGPA: 1.6% → ∼439 students

What stood out for me is

1. 53.6% of the batch is between 6-8 CGPA. The curve peaks at 6-7 and drops sharply after 8.
2. “No CGPA” students are 11.97%* of Foundation. That’s ∼3,286 students - more than the entire 8-9 CGPA group.
3. Only 4.89% have 9-10 CGPA. That’s ∼1,342 students out of 27k.

For context, Foundation is the first level and is known to be not so rigorous. The left-shifted bell curve blows my mind.

But I’m trying to understand: What does “No CGPA” mean in BS grading? Is it due to backlogs/incomplete courses in Foundation, or is it a separate category that gets resolved later? And does it impact moving to Diploma Level?

Seniors or current BS students: Is this distribution typical across terms? If anyone has CGPA data for Diploma/Degree levels, would be interesting to see if the curve shifts right or further to the left?

Posting this just to understand the pattern, not to criticize.
